木箱包裝中的木材需具備天然耐久性

木箱包裝 中的木材質量是很關鍵的。木材的天然耐久性是指木材具有的抵抗生物侵害的能力,是木材本身的一種性質。例如:術材抵抗腐朽的天然耐久性,木材抵抗白蟻蛀食的天然耐久

     木箱包裝中的(de)木(mu)材(cai)(cai)(cai)質量(liang)是(shi)很(hen)關鍵(jian)的(de)。木(mu)材(cai)(cai)(cai)的(de)天(tian)(tian)(tian)然(ran)耐久(jiu)性(xing)是(shi)指木(mu)材(cai)(cai)(cai)具有(you)的(de)抵抗(kang)生物侵害的(de)能(neng)力(li),是(shi)木(mu)材(cai)(cai)(cai)本身(shen)的(de)一種(zhong)性(xing)質。例如:術材(cai)(cai)(cai)抵抗(kang)腐朽的(de)天(tian)(tian)(tian)然(ran)耐久(jiu)性(xing),木(mu)材(cai)(cai)(cai)抵抗(kang)白蟻(yi)蛀(zhu)食的(de)天(tian)(tian)(tian)然(ran)耐久(jiu)性(xing),木(mu)材(cai)(cai)(cai)抵抗(kang)蠹(du)蟲蛀(zhu)食的(de)天(tian)(tian)(tian)然(ran)耐久(jiu)性(xing),木(mu)材(cai)(cai)(cai)抵抗(kang)海蟲蛀(zhu)食的(de)天(tian)(tian)(tian)然(ran)耐久(jiu)性(xing)。對于這些耐久(jiu)性(xing),也分別稱為木(mu)材(cai)(cai)(cai)的(de)天(tian)(tian)(tian)然(ran)耐腐性(xing)、天(tian)(tian)(tian)然(ran)耐(白)蟻(yi)性(xing)、天(tian)(tian)(tian)然(ran)耐(蠹(du))蛀(zhu)性(xing)陛、天(tian)(tian)(tian)然(ran)抗(kang)海蟲性(xing)。b3u東莞市(shi)志成包(bao)裝(zhuang)制品(pin)有(you)限公司

     在學術上,有(you)一種(zhong)觀點(dian)認為:木材的(de)(de)(de)天(tian)(tian)(tian)(tian)然耐(nai)(nai)久(jiu)(jiu)性(xing)(xing)(xing)包括天(tian)(tian)(tian)(tian)然耐(nai)(nai)腐(fu)性(xing)(xing)(xing)、天(tian)(tian)(tian)(tian)然耐(nai)(nai)蛀(zhu)性(xing)(xing)(xing)(抗蛀(zhu)性(xing)(xing)(xing))、對(dui)海(hai)生鉆孔動(dong)物(可以簡(jian)稱為海(hai)蟲(chong))侵害的(de)(de)(de)天(tian)(tian)(tian)(tian)然抵抗性(xing)(xing)(xing)能(抗海(hai)蟲(chong)性(xing)(xing)(xing))。理論(lun)上非常不錯,但由于缺乏足夠(gou)的(de)(de)(de)實(shi)驗(yan)數據,而且(qie)對(dui)沒有(you)白蟻(yi)的(de)(de)(de)國家和地區來(lai)說并(bing)不適合,另(ling)外大(da)多數使(shi)(shi)用(yong)場合并(bing)不是海(hai)事(shi)用(yong)途,因此(ci)這種(zhong)概括性(xing)(xing)(xing)的(de)(de)(de)綜合概念目前還不具備實(shi)用(yong)性(xing)(xing)(xing)。所以使(shi)(shi)用(yong)全稱如“對(dui)腐(fu)朽(xiu)菌的(de)(de)(de)天(tian)(tian)(tian)(tian)然耐(nai)(nai)久(jiu)(jiu)性(xing)(xing)(xing)”、“對(dui)白蟻(yi)的(de)(de)(de)天(tian)(tian)(tian)(tian)然耐(nai)(nai)久(jiu)(jiu)性(xing)(xing)(xing)”等(deng)更(geng)加準確,或者直接使(shi)(shi)用(yong)天(tian)(tian)(tian)(tian)然耐(nai)(nai)腐(fu)性(xing)(xing)(xing)、天(tian)(tian)(tian)(tian)然耐(nai)(nai)蟻(yi)蛀(zhu)性(xing)(xing)(xing)(抗白蟻(yi)性(xing)(xing)(xing))等(deng)特定術語(yu)。東莞(guan)市東友(you)包裝材料有(you)限(xian)公(gong)司
